#DAC of CO2 from the atm. is being explored as a tech. that can contribute to the goal of reaching #NetZero CO2 emissions.
A new study led by @DonglongFu1 showed that the use of zeolitic materials are feasible for DAC when it is integrated with H2O harvesting.

"A combination of a commercially available desiccant, AQSOA-Z02A, and a mordenite-type zeolite (MOR) enables
continuous operation of a designed #DAC system comprised of two
parallel units with a regeneration temperature of 100Β°C," research finds.

"Techno-economic analyses of 12 process
scenarios reveal that the energy requirement of the best scenario
investigated is 71 GJ/tCO2, while the conventional pure zeolitebased system requires 200 GJ/tCO2."

Research declared that, "the optimized system gives a
cost between $246 and $568 per ton CO2 #captured, depending on
the energy costs, while system operates at sub-0Β°C temperatures or with
integration of water harvesting, respectively."
